ABSTRACT: The needs of the use of construction and demolition wastes have increased due to the rapid evolution. The demolition wastes are not properly disposed resulted in very harmful for the environment. Today the use of demolition wastes is in landfill, but this paper represents the demolition wastes in aggregates recycling after use in concrete. In this study, the natural coarse aggregate with replaced various percentage recycled coarse aggregate and cement replaced by the industry waste of fly ash andground granulated blast furnace slag(), after concrete in checked out various properties. The Recycled Coarse Aggregate replaced with 20% of interval upto 60% with Natural Coarse Aggregate. The byproduct is used up to 20% and fly ash is used up to 20%. Different water cement ratio used with all replacement used in concrete. In this paper the water cement ratio of 0.50 and 0.55 were used. INTRODUCTION Day to day new construction is demeaned with raise in population. Cement, coarse aggregate, fine aggregate and water by the making concrete. is making by the various water cement ratio and also various grade of concrete. Cement is the important role for making concrete and also it is costlier than other. There was estimate that production of cement was about 3 billion tons in 2009 and the extended production of cement is about 5.9 billion tons by Cement industry in about 7% of co 2 emitted on atmosphere. So, cement is harmful material for environment. Ground granulated blast furnace slag () is the byproduct of steel plant and fly ash is also byproduct of thermal plant. Both material has some property and also resistance to alkali aggregate reaction. Both material have some property similar to near about as a cement property. So, fly ash and ggbfs is use as supplementary cementitious material in concrete and use maximum amount without change cement properties. Recycled coarse aggregate is obtained by the demolition of structure and rigid pavement. So, Recycled coarse aggregate replaced with natural coarse aggregate. Increasing recycled coarse aggregate replace with natural coarse aggregate resulted in decrease strength. So, recycled coarse aggregate replace with natural coarse aggregate is positive as environment aspect and economical. Recycled coarse aggregate partial replace with natural coarse aggregate. SIGNIFICANCE OF THE WORK In present work is using recycled coarse aggregate with fly ash and with various water cement ratio of 0.50 and Use of fly ash and by the improve performance of concrete. So, maximum percentage replacement of fly ash and and recycled coarse aggregate is use in concrete as with respect to strength.

Fly ash and was replace with every replacement of recycled coarse aggregate. JETIR Journal of Emerging Technologies and Innovative Research (JETIR) 117

6 Whole experiment was done for water cement ratio of 0.55 & From various experiments and results the following conclusion were made: I. Demolition waste is reuse and protects natural resources and decrease the pollution. II. When replacement of fly ash and increase with increase in workability. So, workability is good given by the percentage of fly ash and increase. III. When recycled coarse aggregate increase resulted in decrease in strength. IV. The results are also near the conventional concrete. V. This type of concrete helpful in small and medium type of construction. VI. VII. Fly ash and use by the overall cost can decrease. While increasing in percentage of recycled coarse concrete and fly ash and values of compressive strength, tensile strength and flexural strength are decreases.
